Abstract

differential displacements differential response spectra lifelines seismic ground motions seismic loads seismic strains spatial variation
Seismic loads that result from different expressions describing the spatial variability of the seismic ground motions at the supports of lifelines are evaluated and compared in this study. The analysis considers two spatial variability models, that are commonly used in lifeline earthquake engineering, namely the ones developed by Harichandran and Vanmarcke ( J. Eng. Mech., 112 (1986)) and by Luco and Wong ( Earthquake Eng. Struct. Dyn., 14 (1986)). It is shown that the models produce significantly different seismic loads for the analysis of buried and above-ground lifelines.
